I believe this line
<https://github.com/web2py/web2py/blob/master/gluon/sqlhtml.py#L1499> in
sqlhtml.py is disturbing the way formstyle_bootstrap displays custom
widgets:
parent.components = [widget]
The older formstyles (table3cols, table2cols, etc) all wrap their
controls within a dedicated tag, for example:
_controls = TD(controls, ...)
...
table.append(TR(_label, _controls, _help, _id=id))
In contrast, formstyle_bootstrap puts a help span as a *sibling* to the
controls:
_help = SPAN(help, _class='help-block')
_controls = DIV(controls, *_help*, ...)
...
parent.append(DIV(label, _controls, ..., _id=id))
The result is that, when the form is submitted but has errors, i.e.:
- form.accepts(...) returns False, and
- fieldname is in request_vars,
the DIV which contained controls and _help now only contains the widget.
The styling applied in formstyle_bootstrap is also lost, e.g.:
controls.add_class('span4')
A partial fix might be to wrap the controls in a redundant SPAN in
formstyle_bootstrap:
_controls = DIV(SPAN(controls), _help, ...)
although this would not fix the styling problem.
Is this bug fixable while maintaining backward compatibility? Is there a
fundamental impedance mismatch between the web2py and boostrap approaches
to form layout? I have worked around the problem in my project to some
extent with a custom formstyle, but am still affected by the styling
problem.
Thanks for an otherwise glorious framework.

Jeremy Field
